Digital Elevation Models

Advanced Elevation Series

From city planning to oil production to flood mapping, many industries require the use of high resolution elevation models to complete projects and tasks. The Advanced Elevation Series produces high accuracy Digital Surface Models and Digital Terrain Models that serve as key building blocks for successful exploration, engineering, land management and simulation. This series offers numerous product configuration options for accuracy, resolution, type, and format. With three options, users can select the product specifications that best fit their project's elevation demand.

WorldView Elevation Suite

Accurate elevation models are key building blocks for successful exploration, engineering, land management, and simulation. The WorldView Elevation Suite provides a full perspective for your project area, bundling a highly accurate digital elevation model (DEM) derived from a WorldView-1 and WorldView-2 stereo pair with ortho-imagery. It offers elevation datasets over rural areas of low vegetation using an innovative geophysical technology similar to 3D seismic processing that provides unprecedented accuracy from a satellite-based DEM

Features & Benefits

Engineering-grade accuracy from space In leveraging PhotoSat’s innovative geophysical technology, we provide superior quality for a satellite-derived product that is comparable to aerial technologies in detail and accuracy.

Current informationConduct your operations with recent data using our control or your customer provided high quality GCPs. We’ll work with you to obtain the data within your date specifications to ensure it is as relevant as possible. Utilize our custom tasking capabilities or select imagery from our ImageLibrary.

Global reachObtain elevation models for any country in the world without local access challenges, such as permitting or in-country presence. Our worldwide reach allows more efficient mapping of areas where getting a plane in the air or a team on the ground is too costly, time consuming, or unsafe.

Features & Benefits

Accuracy and Resolution The Advanced Elevation Series is an accurate, detailed elevation model that allows users to identify features that low-resolution and accuracy elevation models would normally overlook.

Focus on Core Business FunctionsWith the Advanced Elevation Series, there's no need for specialized hardware, software, or staffing expertise to create and process elevation models, allowing more time for users to focus on core business functions.

Global AccessNow customers can have access to global elevation data without local challenges, such as permitting or in-country presence. DigitalGlobe's worldwide reach enables more efficient mapping of areas where getting a plane in the air or a team on the ground is too costly, time consuming, or unsafe.

One Stop ShopBundling DigitalGlobe's Advanced Ortho imagery with the Advanced Elevation Series gives users uniformity in quality and accuracy, as well as reduces vendor management costs.

Optional ProcessingDigitalGlobe has developed a number of additional processing options to enhance the Advanced Elevation Series. Whether it's hydro enforcement, road flattening, contours or shaded relief, users can benefit from all of the additional processing their project requires.
